To @ZZ whom t may concern:

Be it known that I, IRVING A. KILMER, a citizen of the United States, residing at Newburg, in the county of Orange and State of New York, have invented certain new and useful Improvements in Barb-Wire Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvenient in barb-wire machines.

The object of the invention is to produce a machine which will do its Work with a steady action and without any jerking or spasmodic pulling of the wire, which will pass the wire through with a uniform tension, and which will automatically regulate the passage of t-he wire so as to keep the machine at a predetermined speed and action.

The invention consists in a barb-wire machine containing, among others, the following salient features: first, a resilient retarding guide-wheel; second, a barb-pusher; third, a positive main-wire-slack take-up, and, fourth, an automatic brake.

Referring to the drawings, Figure l represents a side view of the machine, the twister and reeler being shown in a vertical position. Fig. 2 represents a top or plan view of the machine. Fig. 3 represents an end view of the rear of the machine. Fig. t is a vertical cross-section on the line 4 et, Fig. 2, looking' in the direction of the arrow and showing parts beyond in elevation. Fig. 5 is a vertical longitudinal section through the ceilinghead and adjunctive parts. Fig. 6 is a vertical transverse section on line 6 6, Fig. l, looking in the direction of the arrow. Fig. 7 is an enlarged detail view, partlyin elevation and partly in section, of the mechanism attached to the twister for driving the reel, and the sectional part is taken vertically through the middle of the parts as arranged in Fig. 6. Fig. Sis an enlarged View on line S 8, Fig. 2, looking in the direction of the arrow. Fig. 9 is an enlarged section on line 9 9, Fig. 2. Fig. lO represents a view, with the cap-plates removed, of the method of securing the fixed and movable knives. Fig. 11 is a section on line 1l 1l, Fig. 10. Fig. l2 is a detailed section of the rotative take-up for the barbed wire, taken on line l2 12, Fig. 2. Fig. 13 is a section on line 1S 13, Fig. 3.

In the drawings the letters a c represent legs supporting a suitable frame A, forming spiral spring b3 and a plate b4, the latter being held resiliently against the guide-wheel B by the spring b3, Fig. (i. In Vfront of these guide-wheels the standard a3 carries the fixed guides a5 lf. Y

To the top of the frame A and ata suitable distance from the guide-wheels B B there is secured a bed-plate a6. At the front end of this bed-plate a6 is secured at the middle a plate c.' Rising from this plate c is a standard c-, carrying at its top a round box O, Fig. 5, having its concave ci toward the rear of the machine. This box C is to be closed by a cap O', the box O and the cap O having the two tubular bearings c3 cl along' the middle longitudinal line of the machine and in line with the guide-wheels B B. placed a gear-wheel D, having the teeth d, which project through a lateral opening in the box O and mesh with another wheel D', the location of which will be hereinafter setforth. The gear-wheel D has gudgeons d CZ', which bear in the bearings c3 ct, and through the wheel and its gudgeons there is a continuous central bore c5. W'ithin this bore c5 is placed the'tubular guide E, having its front end e, within the gudgeon cl', and to this end is secured the nipple c2, which has a central passage e3 communicating with the bore e4 of the tubular guide E. Just beyond the extremity of the end c of the tubular guide E the gudgeon d has the circular recess or seat d2. In this seat there is placed a block E', through the central hole e5 of which thc nipple e2 passes loosely. To this block E is secured rigidly the coiling-pin D2, which projects out beyond the end of the gudgeon d. Secured to the outer end of this gudgeon d lVithin the box O isl IOO is a face-plate (Z3, which has the central hole (Z4, through which the nipple c3 passes loosely, and another hole (Z5, through which the coiling-pin D2 passes.

Spaced from and in front of the standard c there rises another standard f, having therethrough the threaded orifice j". This orifice f' is along the middle longitudinal line of the machineand aligned wit-l1 the bore of the gear-wheel D. Into this threaded oricef is screwed, a thimble F, having the central smooth boref3. Into this smooth central bore f2 loosely fits the front end e of the tubular guide E. On the outside of the thimble F and in front of the standard f is screwed an adjusting-nutf3. On the tubular guide E, between the two standards c' andf, is placed a collar G, which is held by set-screws g g, the collar being in line with the thimble F.

On each side of the standard f there is a lug h, to which lugs by a through-bolt h', Fig. 8, there are pivoted the lugs h2 of a yoke H, having the single arm h3, coming up on one side of the collar G, and a double arm 7L4,hav ing the branches hi h3, coming up on the other side of the collar G. From the upper end of the branch h3 there extends inwardly a fork k7, which fits loosely in a circumferential groove g in the collar G. In the branches h3 h6 are tubular bearings h3, in which fit the arbors of a bevel-wheel L9, this wheel coming between the two branches h3 h3. Placed so as to engage the bevel-wheel 71.9 is a cam-wheel H', the construction and location of which will hereinafter be explained. To the single fork h3 is secured one end of a spiral spring hw, the other end of which is secured to the frame of the machine in front of the yoke H.

'lo the rear of the plate c another plate /L'is secured upon the plate a, the front edge t" of the plate 'i coming under the rear end of the bearing Cl. To one side of this bearing and behind the line of its rear end there is fastened to the plate i the block K. This block has in its top the recess k, Figs. l0 and ll. In this recess, at the side nearer the bearing C, there are placed the oblique barbing-wire guide k', which is a strip having the groove k3 in its top, the stationary knife 7c3, which rests in a groove of block K, and the follower Zt", which rests in the recess c and bears against the knife. Against the lear edge of the follower 7a4 is a screw 7c3, which bears against the follower 7c", and two adjustingscrews k3, which bear against the guide 7c'. A cover k7 fits upon this block K. In the bottoni the block K has a transverse recess 7c3, in which is pivoted by a bolt 7c and setscrew kw the tongue Z of the lever L, which projects out from the block and across to the other side of the machine. Projecting from the rear edge of this lever L is a plate Z', having the oblique groove Z3, in which is placed a knife Z3, against the rear end of which an adjusting-screw Z4 bears. A cover Z5 fits upon this plate Z above the knife Z3. The upper surface of the plate Z is slightly above that of the tongue Z of the lever L, and the edges of the plate Z and its cover Z3 and those of the block K and its cover k7, where they are opposite, are curved, as shown. The location of the two knives 7a3 and Z3 is such that their cuttingedges come so near together as to sever the barbing-wire, as will be explained. 0n the lever L on the side of the bearing C away from the knives is the oblique barbing-wire guide Z7.

At the other end the lever L has the fork Z6, which fits into a groove m in a cam-wheel M. This wheel M, as well as the wheels D' and H', are keyed to a shaft M', which runs lengthwise of the machine-frame at one side, as shown, the three wheels being spaced apart, so that each comes at its propel' place in the machine to fit with its engaging part. The wheel H' has the cam-surface h toward the bevel-wheel hf. This wheel ll' has the hub k12 ribbed for lightness, and from this hub there is a stud 7113, to which is connected the pitman n, which extends across the machine below the nipple F and at its other end is connected to a rocker-arm N. This arm N has a hub n', which iits loosely upon the end .0 of a shaft O and is held thereon bya collar n2. This arm N has a pawl n3, and the shaft O has a fixed ratchet-wheel o', by which pawland-ratchet connection the rockerarm engages the shaft.

Rising up from the side of the machineframe are two posts P P', Fig. 9, the former higher than the other, and in both are the bearings p p for the shaft O. To the top of the shorter post P' is hinged a tubular bearing P2,which extends outwardly, and, passing through the top of the post P, terminates on aline with the bearingp. Between the bearings P2 and p is placed a spring p3. In the top of the bearing P2 at the post P is made a notch p3, in which fits the end of a spring 194, secured to the bearing. On this springp4 bears the lower end of the screw p3, which is held in the top of the post P and has a handle p3.

In the 4bearing P2 is a shaft O', the two shafts O and O having the inter-meshing gear-wheels o2 o3. On the projecting ends of the shafts O O are placed the barbing-wirefeed wheels O3 O4. Secured to the frame in front of these wheels is the barbing-wire guide o, and between these wheels and the guide k in the block K there is an oblique guide o3.

Extending out from the rear end of the machine-frame is a bracket Q, from which rises a standard q, having the bearing q', in which turns the shaft M'. Beyond thisbearing this shaft M has on its end the bevel gearwheel on', which engages another bevel gearwheel m2 upon a cross-shaft m3, which turns in bearings Q3 (13 of the forks Q4 Q5, extending out from the standard q. Just within the bearing q2 the shaft m3 has a gear-wheel m4, which meshes with another gearwheel m3 below it and on a shaft m6, which runs parallel to the shaft 'm3 and turns in bearings m7 IOC IOS

Izq

m8 in the forks Q4 Q5 below the bearings Q2 Q3. Outside of thebearing m8 the shaft m has on its end a disk m2, in the outer surface of which there is a diametric groove m10. Fitting into this groove m10 is a slide r, carrying the crank-pin r'. This slide is held to the disk m9 by screws r2, which pass through the slots r2 in said slide r. On the crank-pin r' is a wheel R, having a peripheral groove or provided with Wings, as shown. The position of this wheel R is such that it is in line, substantially, with the bore of the box C and the nipple e2, the said wheel R being off the center of the disk m2.

Outside of the bearing Q3 the shaft m2 has on its end a gear-wheel fm, Fig. 3, which meshes with a gear-wheel s upon a stud s', which turns in a bearing s2. This stud s has upon it inside of the wheel s a pinion s2, which engages a gear-wheel s4 upon a shaft s2, which runs across the machine and turns in bearings s6 S7, depending from the bracket Q. The bearing s6 .97 is secured to the under side of the bracket Q of the machine by the arm S7. The bearing 32 is secured to the bearing s, as shown in Figs. 3 and 13, the two iianges ss s2 being bolted together. The bearing s6 is a long tube, which extends out so that its outer end is below the wheel R. Beyond the end of the bearing` s6 the shaft S5 protrudes and has secured upon it a wheel S, which is similar in construction to the wheel R, though somewhat larger, and the two wheels have the same plane of rotation. Surrounding the bearing s6, at the side of the wheel S, is a sleeve 310, from which depends an arm having the bearing su. In this bearing is a bolt or shaft t, on which is hinged a rocker-arm t'. At the bottom this arm t' has the stud t2, extending ont 4and carrying the loose wheel T, which has the same plane of rotation as that of the wheels R and S.

Secured upon the shaft M', inside of the standard Q', is a sprocket-wheel m12, from which runs a sprocket-chain m12 to another sprocket-wheel m14 on a stud, on which there is another sprocket-wheel m15. Invr the leg a' is made a circular hole or bearing, in which loosely lits the barrel u of the reelingr and twister frame U. This barrel has on the outside a sprocket-wheel u', from which a sprocket-chain u2 runs to the sprocket-wheel m15. In this reeling and twister frame U is placed the reel u2 and the right-and-left-hand screw w1 and traveling guide-wheel uf". The shaft a6 of the reel us has the bevel gear-wheel a7, which meshes with the bevel-pinion u2 on the shaft u2, which is boxed in the frame U and carries outside at the front end of this frame U the gear-wheel uw. This gear-whcelu10 engages another gearwheel um on a stud M12, and this in turn another gear-wheel V. This gearwheel V is loose upon the stud uw, Figs. 6 and 7, which projects from the frame U. The gearwheel V has a projecting hub c, provided with a circular flange o', having the peripheral groove c2. Fitting into this groove r2, one on each side, are the brake-shoes c2 c4. These shoes 12s/t4 are held in place within this groove 'c2 by the elastic strap c5, Fig. 6, whichis pivoted at c, curves down around the under side of .the wheel V, bears against the outer edges of along the machine-frame and has its other end w' secured in the upper end t3 of the rocker- On this rod "W, near the brake-lever v10, is placed a nut 102, and depending from the plate a of the machine-frame is a lug w3, through which the rod W loosely passes. Around this rod W and between the nut @u2 and the lug to2 is'a spiral spring 104.

Two loose pulleys X and X' are secured to the top of the vmachine-frame in front and rear of the plates c and t', there being openings in said frame at thesepulleys. From the standard Q an arm X2 may project outwardly and upwardly and carry a loose pulley X3.

'lhe stud uw ofthe reeling and twister frame U has its bearing in the leg a and has the usual fast and loose pulleys Y and Z, by which power is applied to the machine.y

The operation of the machine is as follows: The main wire to be barbed is fed through the fixed guide a5 and over theguide-wheel B' in the groove b', and the binding-'wire is fed through the fixed guide b5 and over the guide-wheel B in the groove l). Thence the wire to be barbed (and which henceforth will be styled the main wire and the other the binder-wire passes through the bore e4 of the tubular guide E and out through the bore e2 of the nipple e2. Thenceit passes around the wheel R, thence around the wheels S and T over the guide-wheel a5 and to the reel u2. The binder-wire passes under the pulleys X X', thence to the pulley X3, and thence to the pulley T, where it joins the main Wire; or from the pulley X' the binder-wire may join the main wire at the wheel R and go thence with the main wire to the reel and twister. The barbing-wireis fed through the guide o4, betweenV the feed-wheelsO3 O4, these being operated, as will be explained, along the oblique guide 05, and through the guide 7c' in the block K under the stationary knifer;3 and over the end of the movable knife Fand under the main wire, the oblique guide Z7 guiding the end close to the coiling-head and under the coiling-pin D2. NVhen the three wires are in this position, power is applied at the fast pulley Y, and as the reeling and twisting frame U is thus operated through the sprocket-chains u2 and m12 the shaft M' is revolved. This causes the wh eel D' to operate upon the wheel D, turning it. As the wheel D turns, its faceplate CZS, carrying the ceiling-pin D2, also turns, and the latter, engaging the barbing-wire, carries it the desired number of twist-s about the IIO main wire, the wheel D and its connective parts being thus a ceiling-head. The tubular guide E and its 'nipple e2, being loose in the wheel D, may or may not turn with it, this looseness preventing any pull or twist on the main wire. The collar G, being loose in the fork t, can turn with the tubular guide E, and its throw is regulated by the nipple F. The various parts are so timed that as soon as the coiling-pin D2 has completed the due number of turns around the main wire the cam-wheel M moves the lever L upward and the end of the barbing-wire is severed between the movable knife Z3 and the stationary knife 7c3. As this takes place the cam 71.1l of the wheel H', coming in contact with the bevel-wheel h, swings the yoke Il on its pivotbolt 7L', the bevel-wheel reducing the friction. As the yoke ll swings, the fork 7L7 moves the collar G and the tubular guide E and its nipple e2 outward. The outer end of the nipple, coming in contact with the barb, pushes the latter along the main wire and out of contact with the ceiling-pin, thus avoiding any catching while the main wire is being pulled forward. As the cam-wheel ll rotates, the pitman 'n communicates motion to the rockerarm N. The pawl n3 of this rocker-arm N, engaging the ratchet o on the shaft O, causes the latter to rotate. By the engaging wheels o2 o" the other shaft O is also rotated. The barbing-wire fed through the guide ol is caught by the wheels O3 O1 and fed to the ceiling-head. The spring p2 permits a yielding of the bearing P2 upon the bearing 1J, allowing for difference in size of the barbingwire. By the screw p5 and spring p4, with the spring` p2, the two bearings are kept in an elastic relation to each other. As soon as the barb is formed and pushed away from the ceiling-pin the shaft M', through the wheels m m2, shaft m3, wheels m 1 m5, and shaft m, having turned the disk m so that the crank-pin fr has brought the wheel R to its farthest position inward or to the inner extremity of its throw, the said crank-pin fr earries the wheel R outward, pulling with it the main wire7 barbed, and continues so to do until the said wheel R reaches its farthest position outward, or the outer extremity of its throw. Then the wheel R reaches the latter position and starts upon its inner return,the the slack in the main wire, which would otherwise occur, is taken up by the reel a3 pulling the main wire, as will be explained. During the inner return of the wheel R the main wire is stationary at the ceiling-pin D2 and another barb is formed. This operation of the wheel R is continued. It will be noticed that the action of this wheel R is lgiven it by the disk mf and the crank-pin r', the :rotation of the wheel R on the pin o" being to red uoe frietion. As the barbed wire is pulled by the reel a3 with a speed and tension due to the revolution of said reel, controlled as will be explained, the main wire bears with a steady force against the wheel R in the latters entire rotation. As the reel a3 pulls the main wire from the eoiling-head and around the wheels R, S, and T the wheel R moves, as described, and the wheel T moves loosely on the stud t2. The wheel S is driven from the shaft lll through the wheels mfn, shaft on, wheels fm. s, stud s', pinion s3, wheel s, and shaft Si'. This wheel S is driven in the same direction as that in which the main wire is pulled by the reel as. The binder-wire, with the main wire, passes through the hollow barrel u and is twisted and then reeled upon the reel as. The frame U is revolved, and as it turns the reel is also turned and the wheel a5 travels along the screw tot. This causes the main and binder wire to be twisted and wound together around thereel a3. This reel is turned through the mechanism V, a, al", `uib/a, and al. As the wheel V, though loose upon the stud um, engages the wheel a this would cause the two wheels thus engaged to move together with the frame U and not to turn on each other; but the brake-shoes c3 o4, bearing on the flange c', tend to retain the wheel V, allowing the stud am to turn in the latter, whereby, the wheel au turning about the wheel V, the reel a3 is revolved. By means of the lever el the pressure of the brake-shoes es e" may be varied, so as to vary the speed of the reel a. When the reel starts, the coil being at its smallest size, less force is required to turn the reel. Hence there is less pressure of the brake-shoes Us c4 to retain the wheel V. The action of the spring zu* to set the brake-shoes is resisted by the pull upon the rod W through the rocker-arm t', the wires exerting a 'force upon the wheel t2 and pulling it inward. As the coil increases in size the force of this pull tends to diminish, and as this occurs the spring w1 exerts its pressure upon the brake-lever om, and compresses the brake-shoes n3 v4 against the flange o', thus increasing the force applied to the reel as. When it is desired to renew a coil and put in a new reel, the handle fr of the lever 'um is caught bythe catch@13 thereat, and the reel, being loosened, may be moved by hand. In a machine such as described the reel as as it revolves pulls the main wire and the binder-wire through the machine, the rotation of the wheel R allowing for enough slack for the main wire to stop long enough for the barb to be formed without checking the action of the reel and twister. The guidewheels B B being pressed by the spring Il, have a tendency to retard the pull of the two wires, and hence the latter pass firmly and evenly to the machine and with a steady feed. The tubular guide E being loose in the wheel D, any twist or binding of the main wire is avoided, and as the nipple c2 pushes the barb away from the ceiling-pin there is no danger of the barb catching on the pin, as the reel a3 pulls the wire forward. As the wheel R and the main wire are always in IOO IIO

close contact, there is no jerking action, but they move together smoothly. The wheel R also can be adjusted in toward or out from the center of the disk m. As the wheel S is driven positively in the same direction with the traverse of the main wire as it is pulled by the reel as, this wheel S acts as a frictionbrake upon the traverse of the wire.` Should the reel a3 tend to pull the wire faster than the Wheel S is turning, the diiference in speed would have a retarding effect upon the traverse of the Wire,and this retarding effect causes the wire to pull upon the pulley T, operating the brake, as described.

Having thus described my invention, what I claim is- 1. In a barb-wire machine, the combination of a reel at one end of the traverse of the main wire, a guide-wheel at the other end of such traverse, devices for placing barbs upon the main Wire, located between such reel and guide-wheel, and means, such as described, for binding the guide-wheel resiliently against the main wire, whereby such main wire is kept at uniform tension and with a steady feed, as set forth.
